Step 1: Download the macOS Catalina full installer
Tips: Starting with macOS High Sierra, Apple changed its distribution method for macOS. Instead of providing a DMG (disk image file) that users would download and then mount as a virtual disk to run the installer, Apple began distributing the macOS installer directly as an application through the Mac App Store.
If you're trying to upgrade your Mac to macOS Catalina, you just need to run the installer without needing the DMG file.
To make a macOS Catalina DMG file, you need to convert the installer Apple provides. First, download the macOS Catalina 10.15 full installer from the Mac App Store by the link below.
Download macOS Catalina from App Store
Tap Download when it asks whether you want to download macOS Catalina 10.15.7.
When the download completes, click the pop-up window and select "Quit Install macOS" to quit the installation.
